The present invention relates to a roller skate with two rollers arranged one behind the other.

According to the invention, each roller is provided with an axle fork, which is pivotally mounted at the lowest part upon a supporting member inclined at a definite angle to the main body of the skate, and outside the vertical plane passing through the axis of the roller, in'such a manner that it can swing transversely, this 1o lateral movement of the axle fork being resilie ently limited, and the bearing surface of the fork running upon rolling bodies, the pivotal points of the two axle forks being located upon opposite sides of the axes of the rollers and out- 15 side the latter, so that the rollers, in transversing curves, are automatically deflected into the appropriate oblique position, whereas when travel ling in a straight line they are resiliently held in the midposition.

20 One form of the constructon of the invention is illustrated by way of example in the accompanying drawing, in which:

. Figure 1 is a view of the skate from below;

Figure 2 is a side View, partly in section, and

25 Figure 3 is a front view.

In the drawing, the axle fork A of the roller H is, mounted upon a supporting member B, which is inclinedat a definite angle to the main body or upper portion J of the skate. This support- 30 ing member B, together with a carrying piece F, is secured to the upper member of the skate, by riveting for example. At the lowest part of the supporting member B, and outside the vertical plane passing through the axis of the roller H,

35 is mounted a guiding bolt D, about which the axle fork A, with the roller, is rockable in the transverse direction w-b. There is furthermore pivotally mounted upon this guiding bolt D a guiding member E, in which bearing rollers W or bearing balls are guided, which serve to minimize forks.

To this bearing surface 131 of the supporting member B are attached abutment lugs B2 to left and right, by which the deflection of the axle fork when traversing a curved path, is limited.

In order to cushion the axle fork in its lateral 5 deflection, and toreturn it to the midposition when traversing a straight path, there 'is interposed between the abutment lugs B2 and the axle fork, on each side of thelatter, a resilient member G, which may consist; for example of 10 india rubber or metallic springs.

In each roller skate two axle forks with rollers are so arranged that the pivotal points of the axle forks are located on opposite sides of the axes of the rollers, and outside the latter.

What I claim is: i

In a roller skate with two rollers arranged one behind the other in axle forks, the pivots of the axle forks being inclined in opposite directions, in

combination a main body, a supporting member and a carrier piece for each axle fork, said supporting member being inclined at a definite angle to the main body and secured to the latter, guiding bolts provided on said supporting members at its lowest portion and located on opposite sides with respect to theaxes of the rollers and outside the vertical plane passing through the axes of the rollers, rolling bodies and guiding members for the latter, said axle forks and guiding members being pivotally mounted on said guiding bolts, bearing surfaces on said axle forks and said supporting members, said rolling bodies being arranged between said bearing surfaces of said axle forks and said supporting members,

abutment lugs attached to the left and right of v said bearing surfaces of the supporting members, said axle forks being located between said abutment lugs, resilient cushions interposed between" said abutment lugs and both sides of said axle 40 GEORG MEISTER.
